Be it known that wei FREDERICK F. SMITH and Amun ifnunsron, both of Four Corners, iu the countyot` Erie, and State of Ol1io,'have invented certain new and useful Improvements in Seeding Machines; and we` do hereby declare that the following is a full, clear, and exact description of the snme,!reference being had to tho accompanying drawingsl making a portion' of this specification, in which- Figure lis a plan o top view of' a seeding machine constructednccording to my invention.

Figure 2 is n centra! verticalisection of the same:i i y Figure 3 is a detached vertical transverse section of a portion of the same.

Similar letters of' reference indicate corresponding parts in all the figures. f

This invention relates to that class of seeding machines in which seeding stocks or shares are employed to 1` open furrows for the reception ot' seed passed downward through the stocks or shas bjsnitable mechanism; audit consists in a novel combination of a lever with the seeding stocks or shares and the clutches` by `which passage of the seed, may be readily changed in order to ndaptthe machine to sowing or plantingdier'ent quantities or varieties of seedsv l if i To enable others to understand the construction and operation of my invention, I will proceed todescribe it with reference tothe dran-ings. i l l t v The main frame of the machine is shown MVA, and is furnished. with a. draught-pole, A', and supported upon the twodrivngwheels E, each of which is secured upon the outer end of en independent nxle,`a,`these axles a being situated in line with each other, as shown in iig. 1,and furnished, at their inner ends, euch with@ pulley or buud-wheel, b- Situnted at the forward endfof the frame A, in line with eachother and parallel with the axles a, are twoslmfts, B', upon the inner end of` cach of which is secured a. loose pulley, c, whiciimiscou- V nected with the'band-Whccl b, behind it, by a belt, dfY Each of the pulleys c has attached to ont.` side thereof one portion, e, of niclutoh, cf, the sliding partfof which is madre torotate with the shaft B,on whichit is' placed, by means of a longitudinal feather formed upon the said shaft. The sliding part f of eachclutchis i moved by meansof n pivoted arm, g, the forward end of which is constructedwith n yoke, indicated in dotted lines in fig. 1, the ends of which are furnished `With pins, a, which project inward into a circumferentil groove, b, formed `in the said sliding portion fof the clutch. The aforesaid sliding portions 0f. the clutch ef are forced inward toward the other portions thereof' by'a spring/L, attached to the frnmeA, and acting`upo'n the arm g,`

ng represented in iig. 1- C indicates pivoted bcntle'vcrs, thc pivot of each one of which is situated at alittle distance from thc pivot of one of the arms g, at the inner sido thereof, ea'eh of the Said bent leversbeing so arranged, in relation with the contiguous arm g, that when its transverse or rear part (Shown in dotted lines `in iig. 1) is'forced backward it will operate `the said arm to move the portion f of the Clutch connected therewith,

away from `the other portion eoiiithe `said clutch, as will be hereinafter fully set forth. t Situated overthe reef.

moet ends of thc arms [j aldbcnt levers C is n `strong transversetiltin'g hoard, D, the ends of which arc pivoted in suitable bearings formed in the `upper extremities of upriglits, m,`attached to the lateral edges of theframe i A, Oncedge'oi this tilting boni-dis furnished with outwardly lprojecting spurs, n, which extend upwardtwhen i i theniachine is in opcriltOn, but `which, when 'the board is tilted or turned over, ne sho'Wn more clearljr in 2, strike the transverse or rearmost paris of the levers C, and force the same backwards. Attuchedto the sume edge of the tilting board D as `tile spurs n, just mentioned, is n st'o .g coral or chain, 11, which is passeddowhin,

`front of the said board, vand thence back underneath thesame, and has its rearmostextremity attached tothe lever E, which has its ioWCr I)end pivoted to the frame A, and which is situated in convenient proximi drivel-s scat The hollow or tubular seeding stocks areshown nt G, and may be of any ordinary ons construction, andare connected with the forward end of the frame A by pivoted linksor bars, 7j, theses ng stocks being attached to thc rear endsof` `the aforesaid links to transverse pins, r und r- Of `thesetpinsjthe lowermost ones, r,.should be made of metal, while the' uppermist ones, r, which poss over lthc upper edges-of the hairs or links r, ure intended to be made of wood, in order that in the event ofvono of the seeding stocks striking an obstacle with very great or unusual force, the wooden pin r" thereof .will Ibreizhv and allow vthe stock to swing backward, thus preventing zmyserious injury to the machine from the codcifission, Attached tothe rearmost side of euch seeding stock is a.- chain, a, th'eeuppeclind of which ispnssed urndcr the tilting board D,

und issecured to the renrn'iost side o-f tho said tilting board, ns shown in red outlincjih Eg, 2.' By pullingthe -levcrfiil backwards, the cord or chuinp tilts the tilting hoard D, bringing its upper cdge'do'wnwurd, wliich, dr awing, upon the chains s'lifts or clevstcsthe seeding stoclc'lG clear frhm the groundut thesa.me time'tlmt tlhusgpurs n, striking the'trunsverse or rcnr parts of the bent levers @,move .the said rear pu'rts or arms of theiri` re'.-1:1id' u levers back, und thus cause the pirated arm v r1-izo bring the'isliding -purtsf of the, clutches ef :iwuy from theA `othenpnrts e thereof, thus stopping thcmotion of the shafts B', und, inasmuch as the mechanismV by which the flow or passage of the s -ed downward to the seeding stocks isregnluted, ns will be ,presently fully set' forth,

receives its motion from the said shafts B',"it follows'tliut the motion of .the said mechunismis stopped simultaneously with the raising oi' thc seeding stocks G, so thnt o. single movement df thelever lE suiices 'to bring` the several ports into proper position to enable the machine. to be drawn along without operating sume.

Situatedvst the forward portion of the frame A, in line with each of the driving-wheels B, is ai, hopper,l, the

upper part a* of which is mede removable, as will presently be explnined,nnd which may be of any desired or Y suitable form, but the lower portion b* of which is intended to b'e made with dat Sides, nml' has situitted` within 4' it, und working upon-n transverse axis, :t seed-'dropping cylinder, J, which is furnished with Yconica-.l or other suitably shaped mess'uring recesses, u, formed in its circumference nt suitable djstn'nces nparh'un'd the oll'ice of which isg'to curry or distribute the seefhfrom the upper portion of the hopper to t`-l|e`seeding stock situated below the same, thexsnid-stock being connected with the opening in the under s ideiof the hopper by inenns ofaflexible tube, 11'. The quantity of 'seed dropped or passed downward et each revolution of the cylinder J being regulated by the aggregate size of the recesses u, and tho'distanc'e apart it which it isdrop'pcdin the furrow formed by the seeding stock being rcgulnted'by the distances spurt of thedfresaid recesses u, the grain passing to the cylinder between tle two inclined plates C D', situated within the hopper und above the's'nid cylinder. The

inner end of the shaft or pivot ul of each cylinder `J projects through the inner side of the hopper` I, and has u spur-wheel, it', upon it, und gearing into n. similar spurlwheel, y, secured giponx the ndjncent shnftjBQthe scid shaft B thus communicating motion to the cylinders l, or, in otherwOrdS, to the mechanism that regulates the pnsssg'c of the seed throyugh the seeding stocks to the ground, as hereinbefore mentioned. Formedin the outermost side of the lower part In* of eafch hopper is un openingthrough which Vthe cylinder is passed into the saidpart oi' the hopper, thesuid opening being closed by a plete, c*, as shown in iig, Snfnd in which' informed/the I bearing of the outer end of the shaft u of the cylinder. This platelms its top and interni mitunter! in s. Arebote formed around thc `det-responding'edges of the aforesaid opening-'nud the 'boi/telnor loller edge-.thereof is tted in n longitudinal groove formed in the frame A, es shown at' c'f, in iig. -3. YWhen the upper-part a* of the hopper is fitted upon the lower part bf thereof, the lower edge of the said upper phrt a*'exvtenids below the upper edge of the plate c*, und holds the same securely in place when it is desired to remove -the cylinders' J in order to substitute others fitted for dropping wvariety of seed or for dropping the` iced in greater `or-less quantities.' The upper ports qi, of the lho'ppers nre first tken of; the plates c*` are `then removed, und the change of cylinvders may be easily e'ected, so that by this ineens the'mscliine may be djusted for. seeding with any variety of seed with very great facility y i What we clnim as our invention, and desireto secure by Letters Patent, is-

1. So combining the lever E with the4 :seeding stocksl G, and clutches e `f that the movements of the said levers will elevate the scolding stocks simultaneously with the operstion ofthe. clutches to stop the-motion of the seed-dropping mechanism,lsubstuntully as herein zset forth.

2. The retention of the plate c* in. its place with reference tothe cylinder J aud hopper I, by ineens of the groove c"1 undrcmovublc upper port a* of `the nforesuid-ghopper, sub'stantiellyras hereinset forth for the purpose s eciiedn" l i p l "FREDERICK F. SMITH,
